Sidney's father was a cabinetmaker and his mother funded the business venture with Β£50. During the second world war the first night raid destroyed the original 1932 factory and the business moved to its present location in Cricklewood, London. Ronnie Rustin, Sidney's son, took over the business and ran it until his death in 2008. He drove the growth of Rustins to be one of the best brands in the industry with a focus on wood finishing products, speciality paints and decorating sundries. Rustins products sell throughout the UK to home DIY enthusiasts and professionals who want quality and innovative products.

Benefits include Strengthens and Reinforces Wood Moisture Penetration Protection Supports Wood Restoration Review: Great stuff - Gloves & Ventilation is a must, very strong smelling liquid, much like a varnish to use. Drilled a load of holes in a partially rotten back door sill, used a disposable syringe, this product seems to do a decent job at re-hardening rotten wood fibres & binds them back together. Also used this stuff to prime around all the joint of my concrete sectional garage & where it rests on the concrete floor, previous attempts to seal the garage to floor interface have only last a couple of yrs before the sealant lost its grip on the concrete floor, worked well on the inside, I assume the exterior will be just as successful. Found another use for this awesome liquid, this is a temp solution to a leaking garage roof. Old corrugated roofing panels have become porous, cracked in place & started to allow water ingress, jet washed roof exterior, allowed it to dry, painted this liquid liberally on the roof, soaks in well, seems to be a winner, water tested next day, water just beads up & runs off, no more soaking thru to the inside. Also stopped the annual covering of moss that has been a problem as garage is in the shade of trees, so killed 2 birds etc. Only complaint is it's pricey & no-one sells it in larger cans than 250mls. Review: Fumes are very strong, making indoor use quite unpleasant without excellent ventilation - I used Rustins Wood Hardener for Rotted Wood (500 ml) on some areas of exterior timber that had started to soften due to rot. In terms of function, the product does what it is designed to do. It soaks into deteriorating wood fibres and helps stabilise them, leaving the timber noticeably firmer once it has cured. The liquid itself is very thin and penetrates well into soft wood, which makes it effective for consolidating damaged areas before filling or repairing. Application is straightforward with a brush, and it spreads easily over the affected timber. However, the biggest issue with this product is the very strong smell and fumes. The odour is extremely powerful and lingers for quite a long time after application. Even with good ventilation, the fumes are quite unpleasant and can quickly make an indoor environment uncomfortable to work in. Because of this, I would strongly recommend using it outdoors or in very well-ventilated areas only. If you do need to use it inside, proper ventilation and possibly a respirator would be sensible precautions. In summary, it is an effective wood hardener that does its job, but the fumes are significant and something buyers should be aware of before using it indoors. ## Features - Causes serious eye irritation. - Causes skin irritation. - Harmful if inhaled. - Harmful in contact with skin. - Highly flammable liquid and vapour. - May cause allergy or asthma symptoms or breathing difficulties if inhaled. - May cause an allergic skin reaction. - May cause drowsiness or dizziness. - Revitalize Wood Surfaces: Rustins Wood Hardener penetrates deep into wood, revitalizing and strengthening weakened or decaying areas, ensuring a solid foundation for any wood project. - Professional-Grade Stabilizer: Formulated for durability, our wood hardener is a go-to solution for stabilizing and fortifying soft or damaged wood. - Easy Application for Immediate Results: Simply apply and watch as our wood hardener works its magic.

It reminds me of the liquid used for fibre-glass, or perhaps a thin version of PU glue. It's stinky and pretty horrible if you get it on your fingers. It's readily absorbed by wood, and the end effect is rather like painting it with yacht varnish, except it's rock hard in two hours. It sets like plastic so the surface is water repellent and tough. Looks like a varnish, so you may not need any finishing at all, or seems to be a good base for paint. All in all it's a fantastic product. This is the first time I have used it, it won't be the last. I had imagined this to be absorbed like a very thin liquid and to then convert all the soft wood to something really hard. That's not really what it does. Yes, there is some absorption, but not much. It forms a solid, yes, but only the top of the treated wood. So, I think the way to proceed is to thoroughly soak the wood with preservative, then when that's dry, hit it with this to form a water resistant surface that protects and provides a great key for filler. Highly recommended. ## Frequently Bought Together - Rustins Wood Hardener for Rotted Wood - 250ml - Everbuild Multipurpose Wood Filler – Suitable for Indoor and Outdoor Use – Sandable – Light Stainable – 250ml --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/129968548-rustins-wood-hardener-for-rotted-wood-250ml-repairs-rotted-timber](https://www.desertcart.vu/products/129968548-rustins-wood-hardener-for-rotted-wood-250ml-repairs-rotted-timber) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-08*
